This is your URL definition.
r'^(?P<category_name>[a-zA-Z_]+)/(?P<subcategory_name>[a-zA-Z_]+)/(?P<information_name>[a-zA-Z_]+)/$',
views.view_information, name='information'),
As far as I can see it does not allow spaces in the url. But you apparently do have a space in one of your values
'{'category_name': 'Physics', 'information_name': 'Test info', 'subcategory_name': 'a'}'
